Pediatric Sleep Apnea & Sleep Disordered Breathing

What Is Pediatric Sleep Apnea?

Obstructive sleep apnea (OSA) occurs when a child's airway becomes partially or completely blocked during sleep, causing pauses in breathing and drops in oxygen levels. It is more common in children than most parents realize — affecting an estimated 1–5% of all children — and can have serious consequences on growth, behavior, learning, and cardiovascular health if left untreated.

Children with sleep apnea are often not the obvious picture of a "tired" child. Many are instead hyperactive, inattentive, or struggling in school — symptoms that are frequently mistaken for ADHD or behavioral problems.

Signs and Symptoms to Watch For

• Loud or habitual snoring (more than three nights per week)
• Witnessed pauses in breathing during sleep
• Gasping or choking sounds during sleep
• Mouth breathing, especially at night
• Restless sleep or unusual sleeping positions (neck extended, seated)
• Bedwetting in a previously dry child
• Waking with headaches
• Daytime sleepiness, irritability, or difficulty concentrating
• Behavioral problems, hyperactivity, or poor academic performance
• Slow growth or poor weight gain

Causes in Children

The most common cause of obstructive sleep apnea in children is enlargement of the tonsils and adenoids, which narrow the airway during sleep. Other contributing factors include obesity, craniofacial differences, neuromuscular conditions, allergies and nasal congestion, and a family history of sleep apnea. Some children have multiple overlapping causes, which is why a thorough evaluation is important.

Diagnosis: The Sleep Study

The gold standard for diagnosing pediatric sleep apnea is an overnight polysomnography (sleep study), which records breathing patterns, oxygen saturation, brain wave activity, heart rate, and movement throughout the night. Dr. Halani reviews the results in the context of each child's full clinical picture to arrive at an accurate diagnosis and severity classification.

Treatment Options

Treatment depends on the cause and severity. For many children — particularly those with enlarged tonsils and adenoids — an adenotonsillectomy (surgery to remove tonsils and adenoids) resolves or significantly improves sleep apnea. When surgery is not appropriate or does not fully resolve symptoms, continuous positive airway pressure (CPAP) therapy delivers gentle airflow to keep the airway open during sleep. Nasal allergies contributing to congestion are treated in parallel, and weight management is addressed when relevant.

Follow-up is essential: children should be re-evaluated after treatment to confirm resolution, as a portion of children — especially those with obesity or complex anatomy — have persistent symptoms after surgery.

Why Early Treatment Matters

Untreated sleep apnea in children is associated with growth failure (growth hormone is released during deep sleep), elevated blood pressure, changes in heart structure, behavioral and cognitive difficulties, and reduced quality of life. Early diagnosis and treatment can reverse many of these effects.

Frequently Asked Questions

How is pediatric sleep apnea different from adult sleep apnea?›

In children, sleep apnea often presents with behavioral symptoms — hyperactivity, poor school performance, or bedwetting — rather than the obvious daytime sleepiness seen in adults. Enlarged tonsils and adenoids are the most common cause in children.

Does my child need a sleep study?›

A formal overnight polysomnography is the gold standard for diagnosis. It records breathing patterns, oxygen levels, brain activity, and movement during sleep to provide an accurate picture of what is happening overnight.

Is CPAP required for children with sleep apnea?›

Not necessarily. In many children, surgical removal of enlarged tonsils and adenoids resolves the problem. CPAP therapy is used when surgery is not appropriate or does not fully resolve the condition.
